TECHNICAL FIELD

The presently disclosed subject matter relates generally to computer diagnostics. Particularly, the presently disclosed subject matter relates to systems and methods of presenting diagnostic information of an electronic device at diagnostic equipment.

BACKGROUND

Many electronic devices include systems and subcomponents that monitor system health. These systems and subcomponents can generate related information and store the information in memory. This information may be stored as diagnostic information, because it may be accessed by and helpful to a technician or other personnel for diagnosis of errors or other problems of the electronic device. Example diagnostic information includes log data, last-known metrics, and currently-relevant fault conditions.

A server residing at a data center is type of electronic device that can have a diagnostic subcomponent or module that monitors system health of the server. In the instance of an error, failure, or other problem with the server, a technician may be notified or the problem and then go to the server to determine the source of the problem. The technician often carries diagnostic equipment that connects to the server for retrieval of diagnostic information. The diagnostic information and/or analysis information may then be presented to the technician. Based on this information, the technician may then determine how to correct the server problem. The server problem may be corrected by, for example, reconfiguring the server, replacing a component of the server, or repairing a component of the server.

In some instances, a technician may be unable to use his or her diagnostic equipment to retrieve diagnostic information from a server. For example, a diagnostic subcomponent or module may experience power loss such that it cannot communicate the diagnostic information to the diagnostic equipment. This scenario can encumber the technician and reduce his or her ability to repair the server. Accordingly, there is a need for improved systems and techniques for technicians to diagnose problems with electronic devices, particularly servers.

FIG. 1 illustrates a block diagram of an example system 100 that can provide power from diagnostic equipment 102 to an electronic device 104 for communication of diagnostic information in accordance with embodiments of the present disclosure. Referring to FIG. 1, the electronic device 104 may be a server, a desktop computer, a laptop computer, a tablet computer, a router, a switch, a smartphone, or any other electronic device having a diagnostic module 106 configured to monitor health of the electronic device. The diagnostic module 106 may acquire, detect, or receive health-related information from components of the electronic device 104. For example, a component of electronic device 104 may fail, and the diagnostic module 106 may determine failure of the component based on data received from the component directly or by another component that interacts with the failed component. Indication of failure or other health-related condition of a component may be stored as diagnostic information 108 in memory 110 of the diagnostic module 106. Other example diagnostic information includes, but is not limited to, event logs, metrics, temperature, voltage states, physical shock levels, humidity measurements, fault conditions, moisture exposure information, state information of components of the electronic device, and the like. The diagnostic module 106 may include hardware, software, firmware, various other electronic components, or combinations thereof for implementing the functionality described herein. For example, the diagnostic module 106 may include memory 110 and one or more processors 111 for implementing the functionality described herein.

Diagnostic equipment 102 may interface with the electronic device 104 via input/output (I/O) interfaces 112 and 114. I/O interfaces 112 and 114 may be a part of and integrated into electronic device 104 and diagnostic equipment 102, respectively. A cable 116 may operatively connect the I/O interfaces 112 and 114 for carrying data signals (represented by double arrow 118) between diagnostic equipment 102 and the electronic device 104. The cable 116 may also carry electrical power (represented by arrow 120) from the diagnostic equipment 102 to the electronic device 104. Further, the cable 116 may be manually connected to the I/O interfaces 112 and 114 as shown in FIG. 1, or manually disconnected from the I/O interfaces 112 and 114.

In operation when the cable 116 operatively connects I/O interfaces 112 and 114, diagnostic information 108 may be communicated via the cable 116 to the diagnostic equipment 102. Particularly, I/O interfaces 112 and 114 may operate together to communicate data signals 118 carrying the diagnostic information 108 to a diagnostic module 122, where the diagnostic information 108 is processed, analyzed, and presented to a technician or other operator via a user interface 124 of the diagnostic equipment 102. The diagnostic module 122 may include hardware, software, firmware, or combinations thereof for implementing the functionality described herein. For example, the diagnostic module 122 may include memory 128 and one or more processors 130.

In accordance with embodiments, diagnostic equipment 102 may include a power supply 126 (e.g., a battery) operable to deliver power to the electronic device 104 via the cable 116 and I/O interfaces 112 and 114. Power may be delivered to the electronic device 104 to power the diagnostic module 106 such that diagnostic information 108 can be communicated to the diagnostic module 122 of the diagnostic equipment 102. This may be needed, for example, in the instance that the electronic device 104 does not have sufficient power to retrieve the diagnostic information from memory 110 and/or to communicate the diagnostic information 108 to the diagnostic equipment 102. In the instance that there is sufficient power at the electronic module 104, a power supply 128 of the electronic device 104, for example, may provide power to retrieve the diagnostic information from memory 110 and/or to communicate the diagnostic information 108 to the diagnostic equipment 102. The power supply 128 may be a battery of the electronic device 104 or it may be power supplied by an external source, such as an electrical outlet.

FIG. 2 illustrates a flow diagram of an example method of providing power from diagnostic equipment to an electronic device for communication of diagnostic information in accordance with embodiments of the present disclosure. The method is described by example as being implemented by the system 100 shown in FIG. 1, although it should be understood that the method may alternatively be implemented by any other suitable system. Referring to FIG. 2, the method includes receiving 200, at a diagnostic module, diagnostic data or information of an electronic device. For example, various components and sensors of the electronic device 104 may generate diagnostic data or information, which may be acquired or communicated to the diagnostic module 106 of the electronic device 104 shown in FIG. 1. Example diagnostic data or information includes, but is not limited to, event logs, metrics, temperature, voltage states, physical shock levels, humidity measurements, fault conditions, moisture exposure information, state information of components of the electronic device, and the like. The method also includes storing 202, at the diagnostic module, the diagnostic data or information. Continuing the aforementioned example, the diagnostic module 106 may store received diagnostic data and/or information 108 in memory 110.

The method of FIG. 2 includes determining 204, at the diagnostic module, whether diagnostic equipment is connected to an I/O interface. In response to determining that diagnostic equipment is not connected to the I/O interface, the method proceeds to step 200. Otherwise, the method proceeds to step 206. Continuing the aforementioned example, the diagnostic module 106 can determine whether diagnostic equipment 102 is operatively connected to the I/O interface 112 of the electronic device 104. In an example of determining the connection, the diagnostic equipment 102 may communicate a signal via the data line 118 to indicate the connection. When present, a pull-up or pull-down resistor of the diagnostic equipment 102 can be used to provide a known and predetermined signal state to the diagnostic module 106. If the diagnostic module 106 determines that the diagnostic equipment 102 is not connected to the electronic device 104, then the diagnostic module 106 may continue monitoring whether the diagnostic equipment 102 is connected to the electronic device 104.

With continuing reference to FIG. 2, at step 206 the method includes determining, at the diagnostic module, whether adequate electrical power is available from a power supply of the electronic device. Returning to the aforementioned example, the diagnostic module 106 may be operatively connected to the power supply 128 for receipt of power to implement its functionality. The diagnostic module 106 may determine that the power supply 128 has failed or that it is otherwise not capable of providing sufficient power for the diagnostic module 106 to operate or at least communicate diagnostic information to the connected diagnostic equipment 102. In an example, the diagnostic module 106 may determine that the power supply 128 cannot provide adequate power to the diagnostic module 106 by testing voltage provided by the power supply 128. For example, a power level sensor or a line sense signal on the power supply wires into the diagnostic module 106 may be suitably used to determine whether the power supplied is adequate. In response to determining that adequate power is available from a power supply of the electronic device, the method may proceed to step 208. Otherwise, in response to determining that adequate power is unavailable from a power supply of the electronic device, the method may proceed to step 210.

At step 208 of FIG. 2, the method includes using 208, at the diagnostic module, electrical power of the electronic device to communicate the stored diagnostic information to the diagnostic equipment via the I/O interface. Continuing the aforementioned example, the diagnostic module 106 can use power provided by the power supply 128 to communicate the stored diagnostic information 108 to the diagnostic equipment 102 via the cable 116 and the I/O interfaces 112 and 114.

At step 210 of FIG. 2, the method includes using 210, at the diagnostic module, electrical power from the diagnostic equipment to communicate the stored diagnostic information to the diagnostic equipment via the I/O interface. Continuing the aforementioned example, the diagnostic module 106 can use power provided by the power supply 126 of the diagnostic equipment 102 to communicate the stored diagnostic information 108 to the diagnostic equipment 102 via the cable 116 and the I/O interfaces 112 and 114.

Subsequent to steps 208 and 210, the diagnostic equipment has received the stored diagnostic information. Following steps 208 and 210, the method includes presenting 212, at the diagnostic equipment, the diagnostic information. Continuing the aforementioned example, the diagnostic module 122 may control the user interface 124 to present the diagnostic information. The diagnostic information may be presented, for example, by a visual and/or audio technique. For example, the user interface 124 may include a display for displaying the diagnostic information as text and/or graphically. After receiving the diagnostic information, the diagnostic equipment 102 may request additional information and/or provide additional instructions to the diagnostic module 106. The presented information may be condition information for the electronic device 104 based on the diagnostic information. Example condition information may indicate a failed CPU, memory component, or the like. Further, an operator may physically disconnect the diagnostic equipment 102 from the electronic device 104 such as, for example, by disconnecting the cable from one or both of the I/O interface 112 and 114.

FIG. 3 illustrates a block diagram of an example system 300 that can provide power from a laptop computer 302 to a server 304 for communication of diagnostic information from the server 304 to the laptop computer 302 in accordance with embodiments of the present disclosure. Referring to FIG. 3, the server 304 includes a diagnostic module 106 configured to monitor health of the server 304. The diagnostic module 106 may acquire, detect, or receive health-related information from components of the server 304. For example, a component of server 304 may fail, and the diagnostic module 106 may determine failure of the component based on data received from the component directly or by another component that interacts with the failed component. Indication of failure or other health-related condition of a component may be stored as diagnostic information 108 in memory 110 of the diagnostic module 106.

Laptop computer 302 may interface with the server 304 via I/O interfaces 112 and 114. The cable 116 may operatively connect the I/O interfaces 112 and 114 for carrying data signals 118 between the laptop computer 302 and the server 304. The cable 116 may also carry electrical power 120 from the laptop computer 302 to the server 304.

In operation when the cable 116 operatively connects I/O interfaces 112 and 114, diagnostic information 108 may be communicated via the cable 116 to the laptop computer 302. The diagnostic module 222 may process, analyze and present the diagnostic information 108 to a technician or other operator via the user interface 124.

The laptop computer 302 includes a battery 306 operable to provide power to the server 304 via the cable 116 and I/O interfaces 112 and 114. Power may be delivered to the server 304 to power the diagnostic module 106 such that diagnostic information 108 can be communicated to the diagnostic module 122 of the laptop computer 302. This may be needed, for example, in the instance that the server 304 does not have sufficient power to retrieve the diagnostic information 108 from memory 110 and/or to communicate the diagnostic information 108 to the laptop computer 302. In the instance that there is sufficient power at the server 304, the power supply 128 of the server 304, for example, may provide power to retrieve the diagnostic information 108 from memory 110 and/or to communicate the diagnostic information 108 to the laptop computer 302. It is noted that in this example, the diagnostic module 106 may be an onboard management device of the server 302.

In accordance with embodiments, a technician may manually connect the laptop computer 302 to the server 304 via the cable 116 and I/O interfaces 112 and 114 in order to retrieve diagnostic information 108 from the server 304. This connection of the laptop computer 302 and the server 304 may initiate a boot kernel 308 for enabling the laptop computer 302 to access the diagnostic information 108 stored in the server 304. In an example, the boot kernel 308 may provide read only functionality such that the laptop computer 302 may only read the diagnostic information 108 from memory 110 of the server 304. The kernel 308 may operate on the processor(s) 111. Power for operating the kernel 308 to retrieve the diagnostic information 108 and to communicate the diagnostic information 108 may be provided by the battery 306 of the laptop computer 302. The power supplied by the battery 306 may be 5 Volts.

FIG. 4 illustrates a flow diagram of an example method of providing power from a laptop computer to a server for communication of diagnostic information to the laptop computer in accordance with embodiments of the present disclosure. The method is described by example as being implemented by the system 300 shown in FIG. 3, although it should be understood that the method may alternatively be implemented by any other suitable system. Referring to FIG. 4, the method includes receiving and storing 400, at a diagnostic module, diagnostic data or information of server. For example, event log data 310 may be generated and stored in the memory 110 of the server 304.

The method of FIG. 4 includes determining 402, at the diagnostic module, whether a computer is connected to an I/O interface. Continuing the aforementioned example, the laptop computer 302 and the server 304 may initially be disconnected from each other. Subsequently, a technician may connect the laptop computer 302 and the server 304 via the cable 116 and the I/O interfaces 112 and 114. In response to determining that a computer is not connected to the I/O interface, the method of FIG. 4 proceeds to step 400. Otherwise, the method of FIG. 4 proceeds to step 404. Continuing the aforementioned example, the diagnostic module 106 of the server 304 can determine whether the laptop computer 302 is operatively connected to the I/O interface 112 of the electronic device 104. If the diagnostic module 106 determines that the laptop computer 302 is not connected to the server 304, then the diagnostic module 106 may continue monitoring whether the laptop computer 302 is connected to the server 304.

With continuing reference to FIG. 4, at step 404 the method includes determining, at the diagnostic module, whether adequate electrical power is available from a power supply of the server. Returning to the aforementioned example, the diagnostic module 106 may be operatively connected to the power supply 128 for receipt of power to implement its functionality. The diagnostic module 106 may determine that the power supply 128 has failed or that it is otherwise not capable of providing sufficient power for the diagnostic module 106 to operate or at least communicate diagnostic information to the connected laptop computer 302. In response to determining that adequate power is available from a power supply of the server, the method may proceed to step 406. Otherwise, in response to determining that adequate power is unavailable from a power supply of the server, the method may proceed to step 408.

At step 406 of FIG. 2, the method includes using 406, at the diagnostic module, electrical power of the server to communicate the stored diagnostic information to the computer via the I/O interface. Continuing the aforementioned example, the diagnostic module 106 can use power provided by the power supply 128 to communicate the stored diagnostic information 108 to the laptop computer 302 via the cable 116 and the I/O interfaces 112 and 114.

At step 408 of FIG. 4, the method includes using, at the diagnostic module, electrical power from the computer to initiate a pre-boot kernel at the diagnostic module. Continuing the aforementioned example, power provided by the laptop computer 302 may be used to initiate the kernel 308 for operation on the processor(s) 111. As an example, the laptop computer 302 or other diagnostic equipment may send a control signal to the diagnostic module 106 for initiating a diagnostic process for the server 304 or other electronic device. The kernel 308 may be initiated in response to receipt of the control signal. Further, for example, the electrical power of the laptop computer 302 may be used to communicate the stored diagnostic information to the laptop computer 302 in response to receiving the control signal. In an example, a USB 2.0 system can provide 500 mA of power to the diagnostic module 106. In this example, as the diagnostic module 106 begins to load the pre-boot kernel it can establish communication to the laptop computer 302 using the USB data protocol. The kernel 308 can preset the total content of the log as file or a data device. This can be expressed on the laptop computer 302 via the user interface 124 by an application residing on the laptop computer 302.

Subsequent to step 408, the method includes reading 410, by command of the kernel, the diagnostic data. Continuing the aforementioned example, by command of the kernel 308 the diagnostic data 108 may be read from memory 108. For example, event log data 310 may be read from memory 110.

The method of FIG. 4 includes communicating 412, by command of the kernel, the diagnostic data. Continuing the aforementioned example, by command of the kernel 308 the diagnostic module 106 may communicate the read diagnostic data 108 to the laptop computer 302.

Subsequent to steps 406 and 412, the diagnostic equipment has received the stored diagnostic information. Following steps 406 and 412, the method includes presenting 414, at the computer, the diagnostic information. Continuing the aforementioned example, the diagnostic module 122 may control the user interface 124 to present the diagnostic information. For example, a display may be controlled to display the diagnostic information as text and/or graphically. After receiving the diagnostic information, the laptop computer 302 may request additional information and/or provide additional instructions to the diagnostic module 106. Further, the technician may physically disconnect the laptop computer 302 from the server 304 by disconnecting the cable from one or both of the I/O interface 112 and 114.

In accordance with embodiments, a power level supplied by an electronic device may be greater than a power level supplied by diagnostic equipment. For example, the power supply 128 of the server 304 may be operable to provide 12 Volts of power, while the laptop computer 302 can provide 5 Volts. In some instances, the power supply 128 of the server 304 may only supply 5 Volts or lower in the case of failure or other problem. The diagnostic module 106 may be configured to use implement the kernel 308 with both read/write functionality in the case of the electrical power supplied by the power supply of the electronic device being above a predetermined level.

FIG. 5 illustrates a flow diagram of an example method for initiating a kernel with different functionality for accessing diagnostic information based on power supply. The method is described as being implemented by the system 300 shown in FIG. 3, but it should be understood that the method may alternatively be implemented by any other suitable system. Particularly, the method of FIG. 5 is described by example as being implemented by the diagnostic module 106 of the server 304.

Referring to FIG. 5, the method includes determining 500 whether electrical power supplied for a diagnostic module of an electronic device is above a predetermined level. For example, subsequent to connection of the laptop computer 302 to the server 304, the diagnostic module 106 may determine whether electrical power supplied by the power supply of the electronic device above a predetermined level. As an example, the diagnostic module 106 may determine that the power supply 128 is supplying power at 12 Volts, which is above the predetermined level. In another example, the diagnostic module 106 may determine that the power is being supplied by the battery 306 of the laptop computer 302, and that this supplied power level of 5 Volts is less than the predetermined level.

The method of FIG. 5 includes initiating 502 full kernel for control of the electronic device by diagnostic equipment in response to determining that the electrical power supplied for the diagnostic module is above the predetermined level. Continuing the aforementioned example, the kernel 308 may provide read/write functionality for configuration of settings, managed by the diagnostic module 106, related to the diagnostic module 106 of the server system.

It is noted that a full kernel can allow for a user to make changes to settings such as the server boot order, out-of-band network configuration, power and performance settings, and the like. These settings may be stored on a non-volatile EEPROM device connected to the diagnostic module 106.

The method of FIG. 5 includes initiating 504 partial kernel for control of the electronic device by diagnostic equipment in response to determining that the electrical power supplied for the diagnostic module is not above the predetermined level. Continuing the aforementioned example, the kernel 308 may provide only read functionality for only allowing read of diagnostic information 108 such that it may be communicated to the laptop computer 302. In a partial kernel, the ability to make write changes to the non-volatile EEPROM may be limited or prevented. This can be a safety precaution to avoid making changes where the device may be in a state that it cannot safely record or distribute changes to hardware that does not have power.

In accordance with embodiments, a user interface of an electronic device may be configured to present diagnostic information to a user (e.g., a technician). A diagnostic module may control the user interface to present (e.g., display) diagnostic information stored in its memory. For example, the diagnostic module 106 shown in FIG. 3 may use electrical power supplied by the laptop computer 302 or other diagnostic equipment to power the user interface 124 for presenting the stored diagnostic information 108. The user interface 124 may be diagnostic light emitting diodes (LEDs).

In accordance with embodiments, diagnostic equipment may be configured to display an image representing an electronic device and an overlay of condition information via an augmented reality technique. FIG. 6 illustrates a flow diagram of an example method to display an image representing an electronic device and an overlay of condition information via an augmented reality technique. The method is described by example as being implemented by the diagnostic module 122 of the diagnostic equipment 102 shown in FIG. 1.

Referring to FIG. 6, the method includes receiving 600 diagnostic information. For example, the diagnostic equipment 102 may receive diagnostic information 108 from the electronic device 104 in accordance with embodiments disclosed herein. The diagnostic information 108 may be retrieved from the memory 110 and communicated to the diagnostic module 122.

The method of FIG. 6 includes determining 602 condition information based on the diagnostic information. Continuing the aforementioned example, the diagnostic module 122 may generate or otherwise acquire condition information based on the received diagnostic information 108. For example, condition information may indicate a failed component of the electronic device 104. In an example, condition information may review event log and/or sensor state to determine a specific component that is at fault. Further, in this example, the diagnostic may have information about the electronic device and available components and failure states. Further, for example, an Internet lookup may be performed to acquire condition information based on the diagnostic information 108.

The method of FIG. 6 includes displaying 604 an image representing the electronic device and an overlay of the condition information via an augmented reality technique.
